Can only view partial folders & files on Windows 11 & Windows 10 computers.

I am using a Dell Alienware w/Windows 11, Alienware w/Windows 10, and an Android device. A couple of weeks ago I had an issue with Outlook 365 (on my Win 11 device) and had to reinstall it a couple of times. It ended up being a corruption issue that a computer place had to fix for me. During the reinstall process I was prompted to log back into Dropbox which I did. After that point only a small portion of my Dropbox files appear in my File Explorer while all of them continue to appear on Dropbox via Web. When my Win 11 was in the shop, I used my Win 10 computer and was prompted to log back into Dropbox too and the same thing happened. I then used my Android device to access Dropbox via the app and initially all files showed up, but sure enough I was prompted to log back into Dropbox from that device and afterwards could only see a partial inventory of what's there. I just checked my Android again and right now all files are showing up via the app, but still only partial files showing in File Explorer on Win 11 & Win 10 (yes, the Web version stills shows everything and I have logged off and back on via the Web which changes nothing). I have Gigabyte access on the internet (926.27 Mbps D/L & 935.23 Mbps U/L) and both Windows computers appear to be syncing while showing different files and folders. I use Dropbox as Online-Only for my files. Does anyone have an answer and thanks in advance?
